A system for optimizing cache coherence message traffic volume is disclosed. The system includes a plurality of caches in a multi-level memory hierarchy and a plurality of agents. Each agent is associated with a cache. The system includes one or more monitoring engines. Each agent in the plurality of agents is associated with a monitoring engine. The agents can execute a processor level software instruction causing a memory region to be private to the agent. Each of the agents is configured to execute a memory access for data on an associated cache and to send a request for data up the hierarchy on a cache miss. The monitoring engine is configured to intercept request for data from an agent and to prevent snooping for the cache line in peer caches when the cache line associated with a memory region represented as private to the agent.
